Abstract
An insulated joint comprises connecting tubes, a left flange, a hooked jacket, a U-shaped seal ring, an insulating member, an insulating ring, a right flange, a filler layer, binding bolts, and a discharger. The connecting tubes are connected with the left and right flanges. The insulating member is disposed between the left and right flanges. The U-shaped seal ring is disposed at the top end of the insulating member. The insulating ring is disposed on the right flange. The insulating ring is covered with the hooked jacket. Space between the hooked jacket and the connecting tubes is filled with the filler layer. The binding bolts are welded to the connecting tubes and are connected with the discharger through wires. The insulated joint has the advantages that chances of insulation failure of the insulated joint caused by lightning stroke or stray current accumulation are decreased, the U-shaped seal ring has unique properties, precision machining is not required, and machining and mounting are facilitated; a spark gap device is externally connected, the structure is simple, mounting is convenient and fast, the service life of the insulated joint with the structure is prolonged, and safe operation of a long-distance transfer pipeline is ensured.
Description
Technical field
The utility model belongs to oil transport pipeline technical field, particularly a kind of insulating joint.
Background technique
At present, along with urban modernization construction and industrial expansion, under ground piping increases rapidly, the long-distance transport pipes such as petroleum and natural gas (oil, gas, water etc.) lay underground, be subject to for a long time the strong corrosion of outside soil and interior media, and be subject to affecting because of external force the moment of flexure stress rupture occurring, have a strong impact on the trouble free service of pipeline, insulating joint has obtained generally application in long-distance transport pipes for this reason, to ensure the safe operation of pipeline, but because of environment, medium, temperature, pressure, the impacts such as extraneous factor, especially the moment of flexure stress influence that long-distance transport pipes self and extraneous factor are brought, part adopts the insulating joint of "O"-ring sealing to occur because of serious malformation and malfunctioning cause on-insulated of explosive decompression sealing, and puncture the situation that the insulating joint that causes lost efficacy because of thunderbolt or high-tension current, and then affect the safe operation of overall long-distance transport pipes.
Summary of the invention
Adopt the insulating joint of "O"-ring sealing because of the malfunctioning situation of moment of flexure stress influence for effectively overcoming, the utility model proposes the U-shaped seal ring that self can resist serious malformation, ensure the sealing effect of self; For ensureing that long-distance transport pipes puncture malfunctioning situation because the factor such as accumulation of static electricity or thunder and lightning causes insulating joint, adopt externally connected type electric spark clearance device simultaneously, effectively avoided electric current to puncture the situation that causes joint fails.
The technical solution of the utility model is achieved in that this insulating joint comprises adapter, left flange, hook overcoat, U-shaped seal ring, insulating part, dead ring, right flange, packed layer, connection bolt, electrical discharger; Take over and connect left flange and right flange, between left flange and right flange, be provided with insulating part, the top of insulating part is provided with U-shaped seal ring, on right flange, be provided with dead ring, dead ring overcoat has hook overcoat, between hook overcoat and adapter, be filled with packed layer, in adapter, welding connection bolt, connects electrical discharger by wire.
Described packed layer is epoxy resin filling layer.
The beneficial effects of the utility model: in long-distance transport pipes, reduce the insulating joint seal failure that causes the factors such as excessive, the explosive decompression of moment of flexure stress to bring " O " RunddichtringO form because of various complex situations, and reduce because thunder and lightning shocks by electricity, stray electrical current accumulates the insulating joint insulating property that cause and lost efficacy, while is because of the characteristic property of U-shaped seal ring, do not need precision machining, convenient processing and installation; Electric spark clearance device adopts externally connected type, and simple in structure, it is convenient to install, and adopts this structure to improve the working life of insulating joint, and then has guaranteed the safe operation of long-distance transport pipes.
